TURBINE SPRINKLER Filed March 5, 1946 HECTOR F UNGE Inventor Attorneys Patented Apr. 25, 1950 TURBINE SPRINKLER Hector F. Unger, Hood River, -reg.; Dolores Jane Unger, executrix of said Hector F. Unger Application March 5, 1946, Serial No. 652,032

2 Claims.

This invention relates to an apparatus for distributing liquid, and more particularly to a Sprinkler nozzle.

A primary object of the invention is the provision of means whereby a spray may be thrown at such times as water pressure is very low due to great drain on the water supply such as in summer time when water is being used in great quantities and which at the same time will operate as desired under normal pressure.

A further object of the invention is to provide a sprayer which will throw a comparatively low spray in order to saturate the ground without wetting such fruit, fruit trees and other foilage which should be protected from wetting during extremely hot weather.

These, together with various ancillary objects will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure l is a sectional elevational View of a sprinkler,

Figure 2 is a top plan view thereof,

Figure 3 is a bottom plan View of a turbine head of the sprinkler.

Figure 4 is an elevational view, partly in section, of another form of the invention,

Figure 5 is a bottom plan view of Figure 4,

Figure 6 is a detail bottom plan view of the turbine of Figure 4,

Figure 7 is a view similar to Figure 4, illustrating another modification,

Figure 8 is a top plan view thereof, and

Figure 9 is a bottom plan view of the turbine head of the device illustrated in Figure 7.

In Figures 1 to 3 of the accompanying drawings is illustrated one form of this invention and which consists of a nipple l0 internally screwthreaded as at H throughout the major portion l2 of its body which at its upper end 13 is provided with a thick wall l4 having a series of annularly disposed bores 15 and a central, screwthreaded bore l6 to receive the threaded end I! of a screw bolt 18, the upper portion IQ of which is smooth to form a pintle upon which a turbine head of the sprinkler 2| rotatably mounted.

The turbine 20 is provided with a series of equally spaced apertures 22, 23, 24 and 25 extending from the bottom 26 of a relatively thick wall 21 to side outlets 28, 29, 30 and 3| and V- shaped outlets 32, 33, 34 and 35 in its top Wall 36. These apertures are providedwith inclined bottom walls 31, 38, etc., and vertical inner side walls 39, 40, etc., and annular side walls 4| and 42 formed by the tubular casing 43, The depending apron M of the turbine normally overhangs the annularly reduced upper terminal 45 of wall i which reduction forms an annular seat 5! upon which the lower edge 41 of member 43 is adapted to seat. The bore 48 in the turbine is provided with an outercounterbore 49 adapted to receive the enlarged head 50 of pintle [4 which head is provided with a slot 5| for a screw driver in order to adjust vertical limit of movement of the turbine thereon.

The proper operation of the sprinkler depends upon the angle of the walls 31, etc., together with the cooperating vertical walls 40, 4|, etc., the latter providing a retarding action of the turbine without which its speed would be so great that it would throw only a mist so fine that it would be carried off by the slightest breeze and thus fail to water the required area and would not accomplish anything approaching a .raindrop sprinkling action.

It is to be noted that the pintle IQ of Figure 1 may be adjusted to permit the edge 41 or turbine to raise to a fraction of an inch above surface 46 of member 45 to permit a thin unbroken sheet or wall of water to pass through the annular space thus formed.

In Figures 4 to 6 is shown a modification of the above described sprinkler and in these views the nipple 53 conforms to nipple ID with the exception that its upper surface is recessed as at 54 and is provided thereby with an annular rim 55 having a chamfered inner surface 56, the purpose of which is to throw spray passing between the said surface 54 and the turbine head 57 away from the sprinkler and thus prevent forming a pool of water at the base thereof. This turbine 51 has no outer wall as in the first form of the device as illustrated in Figures 1, 2 and 3, but throws a similar type of spray. This turbine 51 is provided with the spaced inclined Walls 58, 59, etc., upon which water is directed by the apertures of the nipple 53 and which will be thrown out almost entirely through the side openings BI and which will be thrown out as a spray in similar manner as by the device as illustrated in Figures 1, 2 and 3. The lower corners 62, 63, etc., of the walls 58 and 59 are beveled ofi to fit the chamfered surface 56.

In the modification disclosed in Figures 7 to 9 of the drawings the nipple 64 is identical with nipple 53, however the turbine 65 has its passages 66, 61, 68 and 69 formed in swastika-like arrangement, each with upwardly inclined walls "1, ll, etc., between vertical walls 12 and 13, etc., pro- 55 viding water passages with exits 14 only in the side wall 15 of the turbine, thus throwing water in a nearly horizontal direction, thereby avoiding throwing water upon foliage much above the ground level which is extremely desirable in many cases, the top wall 16 of the member being imperforate except for the bore 11 for the pintle 18 upon which it operates. The lower outer edge 19 of member 65 is beveled as at 80 to conform to the chamfer 56.

Since numerous modifications will readily ocour to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiments of sprinkler nozzles shown and described, but all suitable modifications and equivalents may be resorted to which fall within the scope of the appended claims.

Having now described the invention, that which is claimed to be new and desired to be procured by Letters Patent is:

1. A sprinkling device comprising a nipple having an apertured end wall, a pintle having an enlarged head supported by said wall, a turbine journaled on said pintle, said turbine having passages opening in its periphery, said passages having inclined walls and straight vertical walls for dispensing fluid in a direction substantially perpendicular to said sprinkling device, said nipple having a recessed upper end Within which said turbine seats, said turbine having a recessed upper end containing said enlarged head of said pintle.

2. A sprinklin device comprising a nipple having a recessed end wall with a centrally disposed threaded aperture, a plurality of circumferentially spaced apertures disposed about said centrally disposed aperture, a pintle having an enlarged head and a threaded base, said threaded base be- -11'ig secured to said nipple in threaded engagement within said centrally disposed aperture, a turbine mounted within said recessed end wall of said nipple and rotatable about said pintle, said turbine having a plurality of passages opening into its periphery, said passages having inclined walls and straight vertical walls, said passages thus dispensing fluid in a direction substantially perpendicular to the axis of said sprinkling device.
